The Giants have the 29th defense againt the pass, allowing 233.8 yards per game. In their last three games they've allowed 939 yards. 423 against Winki (I know), 257 against Romo, and 259 against Young.
Redskins have the 22nd defense againt the pass, allowing 216.6 yards per game. In their last three agmes they've allowed 164 with Garcia, 122 on Vick, and 168 against Delhomme, meaning their defense against the pass is doing pretty good lately, but the QBs they've played against are not great.
Carolina has the 10th allowing 194.1 yards per game. Last three games: 172 vs. Eli, Garcia had 312, and Campbell had 118.

The only one of those defenses that truly sucks agianst the pass is the Giants, the Redskins is terribly ranked, yet they've been getting better. I think Breeks is going to be about 200 or 100 yards shy of 5000.
